BILLIARD-CUE TIP.

Application filed April 28, 1927. Serial No. 187,357.

This invention relates to means for holding tips upon billiard cues. The ordinary tip is cemented, glued or otherwise attached in like manner to the end of the billiard one and this tip is liable to come off, and when the tip is oil", the cue cannot be used until a new tip has been cemented thereon. It has been proposed to provide detachable tips, but these tips usually act to weaken the end of the cue to which the tip is attached and the one is liable to split at the end. It has also been proposed to use tips having screwthreaded shanks, but in these, the impact of the cue against the billiard ball is very liable to deface the screw and cause the screw to jam in the threads of the cue.

Our invention is illustrated in the accompanying drawings, wherein Figure 1 is an elevation of the device; Figure 2 is a section on the line 2-2 of Figure 1;

Figure 3 is a section on the line 33of Figure 2;

Figure 4 is a View of the end of the one illustrating the tapered slot;

Figure 5 is a bottom view of the tip.

Referring to these drawings, 10 designates the cue proper, 11 designates a collar fitting over a reduced portion at the end of the cue and 12 designates the tip. The cue is slightly tapered and the end of the cue is reduced in diameter so that the collar 11 is flush with the outer face of the cue and the inner end of the collar 11 fits against a shoulder 13 on the cue. The outer end of the cue is formed with an under-cut or dove-tailed groove or slot 14 which is not only under-cut but it is tapered being wider at one end than it is at the other, and the tip 12 is formed with a dove-tailed tapered rib 15 adapted to fit the tapered dovetailed groove 14 so that when the tip is forced into place, it is held firmly by a wedging action and cannot be pulled directly ofi, but must be knocked out of place before it can be removed. The tip fits flat against the extremity of the cue and the groove or slot in the end of the one so accurately fits the rib 15 that no joint is visible when the tip is forced into place. The collar or ferrule 11 fits over the tapered slot and dove-tailed rib so as to lock the tip firmly in place against any lateral movement until the col lar is removed. Thus it will be seen thatwhen the tie is in place it cannot be removed eXcept by removing the collar and then driving out the tip. The tip may be of any suitable material, as for instance a felt or rawhide hemispherical body mounted on a suitable base, or the felt may be itself formed to provide the interlocking rib 15. It is to be particularly noted that not only does the collar act to lock the tip to the cue, but it prevents the end of the cue from splitting. This, we regard as a very important feature of our invention.

We claim o 1. A billiard cue, a tip therefor, the tip andcue being formed, one with a dove-tailed rib and the other with a clove-tailed slot into which the rib fits, and a collar fitting over the end of the cue and extending across the interlocking slot and rib.

2. A billiard one having its outer end reduced in diameter and having its end formed with a clove-tailed slot tapering from one end to the other, a tip coacting therewith having a. dove-tailed rib fitting the slot and tapering from one end to the other, and a collar fitting over the reduced portion of the one and extending over the interlocking joint between the rib and slot.

, 3. A billiard one having the small end reduced in diameter, the end face of the one being formed with a dove-tailed slot de-,

creasing in width from one end to the other,

a tip ooacting therewith having a dovetailed rib fitting closely within the dovetailedslot and tapering from one end to the other, and a metallic collar fitting the reduced end of the cue and extending to the end face of the cue to thereby cover the interlocking groove and rib.

In testimony whereof our signatures.
